Neo Geo

  
Neo Geo





 Neo-Geo is the name of a cartridge-based arcade and home video game system released in 1990 by Japanese game company SNK. The system offered comparatively colorful 2D graphics and high-quality sound. A major platform for arcade games at the time, the system was also available as a costly home console. The two versions of the system were known as the AES (Advanced Entertainment System, the Home Version) and the MVS (Multi Video System, the Arcade Version).

The Neo Geo was marketed as 24-bit, though it was technically an 8/16/32-bit multiprocessing system.
